How Ryan Tannehill and other QBs compare in passer rating, PFF grading and QBR

Ryan Tannehill and Andrew Luck's success this year is varied depending on the rankings and gradings (Allen Eyestone / Post photographer)

There’s an identity crisis going on in Indianapolis. Apparently some so-called Colts fans are pulling for Denver’s Peyton Manning in his return to Indy. Colts fans have a real soft spot for Manning considering that their only sustained success since moving to Indianapolis came with Manning at the helm.

But rooting for the opponent? And it’s not like second-year Colts QB Andrew Luck is struggling. In fact he is currently graded as Pro Football Focus’ No. 2 QB behind, of course, Peyton Manning. If you think No. 2 seems high for Luck, you’re not alone. Luck is only 13th in passer rating, but Pro Football Focus factors in many variables from running, throw away passes, batted passes, etc, etc.

So that got me comparing the three QB systems which also includes QBR, the Total Quarterback Rating that ESPN devised to take over the passer rating but has never really caught. Luck is also high in QBR which factors in things like the “clutch factor” as well as overthrows, underthrows and yards after the catch.

Miami’s Ryan Tannehill is high in PFF grading (t-8th with Aaron Rodgers) but only 17th in passer rating and 21st in QBR.
Here’s a look at the three ranking systems. QBs with only one start this season were excluded.
